Contains nonessential genes, used infrequently or under special conditions.

F (fertility)

kind of plasmid

contains genes that promote own transfer from donor bacterium to recipient.

R (resistance)

kind of plasmid

carries antibiotic resistance genes, can be transferred from donors to recipients.

conjugation

process of gene transfer

donor cell

transfers some of its genetic information to other cell,(RECIPIENT CELL)

Conjugation pilus

aka conjugation tube

genetic information travels thru this to recipient cell.

connectes donor to recipient

3 kinds of cells seen in conjugation

donor cell-contains F plasmid

recipient cell-receives DNA does not contain f factor

exoconjugant cell-produced by conjugation.

exconjugant cell

produced by conjugation, is essentially recipient cell that has had its genetic content modified.

IS

insertion sequence elements

mobile segments of bacterial DNA that are capable of transporting themselves throughout bacterial genome.

episome

Circular DNA elements like plasmid

can replicate independently of bacterial chromosome

can integrate into bacterial chromosome and replicate as part of chromosome

relaxosome

f factor produces such protein after contacting conjugation pilus

binds to origin of transfer (oriT)

rolling circle replication

unidirectional mode of DNA replication used to replicate circular plasmid, in which replicating circular molecule appears to reel off its nontemplate DNA Strand, using other as template for replication

origin of transfer (oriT)

site within fertility factor sequence where transfer to recipient cell is initiated.
